摘　　要：目的探讨64排螺旋CT增强扫描在肺栓塞诊断中的价值。方法收集我院2009年6月—2012年12月32例患者,所有病例均行64排螺旋CT平扫及肺动脉CT血管造影(CTA)增强扫描检查,并进行图像后处理,观察血栓累及部位、表现形式及其他改变。结果 32例患者的CT图像均能对栓子的形态、密度,栓塞部位、范围及局部狭窄程度充分显示,CT表现为肺动脉内不规则斑块状及附壁样充盈缺损,斑块周围有或无高密度对比剂包绕。结论 64排螺旋CT增强扫描时间短,图像显示清晰,有多种图像后处理技术可供选用,是目前诊断肺栓塞的首选方法。Objective To study the clinical value of 64-slice enhance spiral CT scan in diagnosis of pulmonary embolism.Methods From Jane 2009 to February 2013,32 patients with PE underwent 64-slice spiral CT and CT angiography and all the data of CTA were retrospectively analyzed to study the involved location,feature and other changes.Results 64-slice spiral CT clearly showed the sites,extensions and stenosed lumens of PE in all patients.On CTA images,PE lesions appeared as intraluminal irregular-plaque shape and adhered-mural filling defects whose periphery was probably encased by the contrast medium with hyperdensity.Conclusion 64-slice enhance spiral CT is the first choice for diagnosis of PE for the short time,clear images and more choices for retrospectively analyse.
